What is the Zero Movement?
ZERO was an art movement founded by Otto Piene and Heinz Mack, aiming to develop into a large international and cross-border movement. The name ZERO originated from a magazine founded by Heinz Mack in 1957, which became a platform for the group's ideas. The magazine was published for several years before ceasing in 1967. The ZERO movement sought to create a new beginning in art, emphasizing light, space, and movement, and became influential in post-war European art.
